Strangely, you did not mention that LA has had 15 earthquakes in the 4.0 range so far this year. Three of them have woken me up in the last 2 weeks. This is the highest number of quakes we have had in recorded history in this period of time.
@@Argelius1 We were waiting for ‘the big one’ when I was kid LA/SD ‘50s-60s ..there was some rumbles,we were ‘familiar’ with smaller ‘rumbles’ ..could happen tomorrow or next century ..
@@Argelius1 Exactly. Humans struggle to comprehend so many things that take place over time periods longer than "years." Geologic time isn't measured in months or years.
I suppose my concern is about people who believe "it will never happen. I've lived here X number of years and..." Like the folks in New York who mocked the weather forecast before Sandy, only to cry and say "I never thought it would be this bad!" Or folks around New Orleans who snickered about a major hurricane hitting their city with "They always turn away at the last minute." Until Katrina didn't. Being prepared when you have time to work with is not "living in fear." It's being ahead of the game. I remember our family tradition growing up in Florida. First day of summer vacation the whole family went hurricane shopping. We got our stock of food and water for three days together, got fuel for the Coleman stove, plywood for the usual purposes, etc. The times we got hit and didn't evacuate (which we did on occasion) we sat in the front yard beforehand and watched everyone frantically running to Home Depot and grocery stores and panicking because all the batteries and water were sold out. If there was no storm, we had a big cookout the first of November and built a new doghouse for our dogs out of the plywood. Nothing was wasted. Nobody panicked because we "didn't think it would actually happen to us." Wonder who would be scoffing about bolting that heavy bookcase to the wall after it fell over on their kids if "it" did happen. You know what they say about hindsight...
What really worries me is that the Los Angeles Basin has a bunch of earthquake faults that are much shallower to ground level than the San Andreas Fault. These shallower faults means even a Magnitude 7.5 quake could cause a huge amount of destruction and casualties on their own.
I remember in a geography of CA class I took in 2010 that the "big one" could happen at any time on a geologic time scale. Meaning, it can happen any time in the next few hundreds of thousands, if not millions of years.
or more likely never as all those vulcanic placess are now more or less death after the big earthquake was in california .... SO IT HAD BEEN already and NOT GOING TO
Human Time vs. Geologic Time. The southern San Andreas can have intervals of 100 years to 400 years between events. Your Grandchildren may miss the next one. Besides - the splinter faults closer to populated areas likely pose a bigger danger
exactly. the Newport-inglewood fault could disrupt all 6 major highways on the west side. we also have a major off shore strike-strip fault that runs from santa monica to the mexican boarder that isn’t widely understood, but they know it can produce upwards of a 7.9.
I grew up in Southern California and experienced the February 1971 Sylmar (San Fernando) earthquake at age 7. It hit right at 6:00 AM PST, and was of magnitude 6.6. I lived about 33 miles from the epicenter so it wasn't bad where I was. It was severe enough to kill 65 people in the San Fernando Valley area, most of them in the Olive View and VA hospitals. We were VERY lucky that it happened at 6 AM and not an hour or two later, when the freeways would have been clogged with cars. Overpasses collapsed at the junction of the 5 and 210 freeways. It would have been hundreds dead, if not more.
I was 13, and lived 9 miles from the epicenter of the 71' Sylmar quake. And l have been through every other major earthquake in Southern California including the Northridge, Whittier, Landers, Big Bear etc. All of them within 30 miles of the epicenters !. The Big One, will make all of those seem like a tremor. It will be the most traumatic experience any individual will go through in their lifetime. Even soldiers that have been to war !.
@@Novastar.SaberCombat I lived in Sand Canyon just over the hill from Sylmar when the 71-quake hit, I was a mile from the epicenter, and it was my very first earthquake experience!
Here in New Zealand, we're also waiting the "The Big One" to send our capital city of Wellington back underwater. In 2011 a big one hit... and destroyed Christchurch, a city previously thought of reasonably safe. This would be the equivalent of expecting a big quake to hit Los Angeles, only to have Las Vegas get destroyed instead.
@@rad4924 I was scrolling the comments looking for a kiwi to comment about how 'we are waiting for "Our The Big One." to hit Wellington.' while shaking my head no why do you have to question where is it. Completely agree with what you said about Christchurch they thought they were safe and then got hit by three big quakes in span of 18 months and 1000s of aftershocks for years after. Everyone thought the South Island was safe from big quakes, since most active fault lines were in the North Island.
I'm 50. When I was in elementary school, there were urban legends of "the big one" where California was going to break off and fall into the ocean, just like at the beginning of this video. We used to do "earthquake drills" to prepare for it. So I can say with confidence that this talk of "the big one" has been going on for at least 40 years.
Yeah but it is gonna happen just we dont know when so being ready is the best thing we can do. At this point if it dose happen 95% of people are absolutely FUCKED because NO ONE is ready. Everyone thinks im crazy but it will ALWAYS be better to be SAFE THEN SORRY. Geological time is wild and we will never be able to fully predict it we can just be ready for when it happens. But sadly i dont think hiding under a school desk if gonna save ANY of us californians esp with how everyone thinks its a joke now. All i can say is god help us when it happens because no one thought the hurricanes the us just had were gonna be bad either and now look at the destruction thats caused. We can NEVER know when its gonna happen. We CAN just be ready.
I'm 66 years old and I grew up with the same stories .when I was 9 years old in 1968 I had heard that the big earthquake was suppose to sink California into the ocean.
@@MilIMeta Correct, they like to re-enforce their Media-Hype position to instill fear and confusion amongst the public. They will create fear to sell their "service".
I was in the Primm Valley Casino (on the Nevada-California border) when the Hector Mine earthquake struck on October 16, 1999. The giant chandeliers swayed back and forth, the floor rumbled, and dust fell from a trembling ceiling. Some people fled the casino, but no damage resulted from the magnitude 7.1 quake. Since that time, I've felt a few gentle rollers here in Las Vegas. But they didn't originate from the fault lines located right here in the city.
Watching from Los Angeles we have had a bunch of smaller 4-5 point quakes recently too. A little more than what feels normal at least to someone who’s lived here for decades. That could be part of it as the smaller quakes could be releasing some of that potential energy. Malibu, South Pasadena and other areas have been hit with quakes that size recently and felt them all in the downtown area very strongly.
@@scottclapson exactly. we’ve been getting a lot of earthquakes lately, and even though they’re just rumbles it makes me wonder if the big one is coming soon
I think the West Coast oughter more worry about the Cascadia than the San Andreas. Cascadia will be the more disastrous that'd make the worst the San Andreas can do look minor in comparison.
Agreed though it very well could trigger the San Andreas as well. CSZ isn't talked about enough but it does finally seem to be getting more recognition the last decade
@ Yup, I'd be VERY surprised when the Cascadia does cut loose that it doesn't trigger reactionary slips in the surrounding fault lines. The earth is one big complex tangle of interlocking plates. If a big one cuts loose in one spot, that's bound to affect the tensions in the surrounding plates' fault lines.
This video was disappointing. Talks very little about San Andreas for the first 10 minutes. Never says why they expect there to be a big one, never shows if any criteria has been met, and never shows any clues to whether or not it’s getting close.
Agreed. And all the focus on the Salton Sea!!!! The Salton is very very shallow - avg 26 feet. It's not like removing the "weight" of it will matter much. That valley was completely dry from 1500 to 1907, don't forget.
I agree also. 15 minutes of backstory only to say we don’t know. Clickbait. This author is “pushing” videos on Instagram so I’m going to block that user.
@@eraymonds We know the Salton Sink has gone through periods when it was "full" and "bone dry" over the last several thousand years, depending on in-flow from the Colorado., just as there was no singular "Ice Age" but a serious of them over the past million+ years, I suggest reading more.

Never mentioned the "Landers/Big Bear " twin quakes ! 7.3 and 6.6 3 hours apart. One dozen aftershocks above 5.5 over the next 2 years. Then 6 years later in the same region, the 29 palms 7.0 . There was really something going on in that region of Southern California at that time. It tore a crack in the earths crust 56 miles long with up to 12 feet displacement.
I remember visiting California in 2019 during the Ridgecrest earthquakes-felt a small tremor but nothing like the 'Big One' everyone talks about. It's surprising how it hasn't happened yet, despite all the predictions!
there are no real pridictions just news hype as long as california has regular earrth quakes to relive stress on the san andreas things will be ok the coastal plate is moving north and will always do that . the worst thing is to not have small earthquakes which will make the big one worse.
I live in Michigan and like 10 ish years ago we actually had a tiny earthquake and I felt it! I was sitting in my kitchen and felt my house wobble slightly, at first I thought maybe the washing machine was unbalanced. I'm so glad we don't have big serious earthquakes here!
As somebody from Mississippi, I am glad that we don't got earthquakes too! 😂👌 Hurricanes are our own catastrophic events that is even more scarier. Same way with tornados but tornados happen out of nowhere randomly just like earthquakes.
The BIG ONES occur on subduction zones. SoCal is nowhere near a subduction zone. The type of shaking for minutes just dont happen nearly as often and if a large quake occurs, it lasts for seconds, not minutes
Actually, there are two plates off the North California coast that are subducting which have created at least two known volcanos: Mount Lassen and Mount Shasta.
@BelwonsenorSimpkriss NoCal ...yes... not SoCal ....though there is a lesser known super volcano which forms the mono lake area. Im convinced if the moon did form from Earth colliding with another smaller planet, the ring of fire is the scab.
@@quaoar213 Interesting idea. That or maybe the impact was a little to the east over Micronesia which may have been an intact continent before the event.
At least the highest the San Andreas can produce is 8.3. I think people should be more focus on Cascadia (The really Big One) rather than just California because that can produce tsunamis unlike San Andreas.
I remember the Tool song begging for the end of LA, "one great big festering neon distraction, I have a suggestion to keep you all occupied, Learn to Swim Learn to Swim Learn to swim."
I sometimes feel earthquakes here in SoCal. I’m afraid the big one will come minutes after a smaller one. Knowing myself I’m sure I’m going to end up sleeping through the big one. Had so many mornings when my family would ask “did you feel the earthquake last night?”
In 2011, The Washington D.C. area experienced a minor quake. I live in Maryland and we felt it. It wasn't that bad, but it did cause some cracking damage to the Washington Monument and some other stone buildings in the area. I also heard some say the foundation of their houses were cracked.
I lived in Northern Virginia then and remember it! As a native Californian, I was so freaked out to feel a significant shake on the opposite coast and I remember seeing the cracks in the Washington Monument. A quake doesn't have to be very large to cause problems in that area!

The 1906 San Fransisco earthquake is when the entire city committed Insurance fraud, nobody had "Earthquake Insurance" but a lot of folks had "Fire Insurance" so the city burned for 3 days
@@rayrayrun Not very good, they used horse back then. Plus Some of the fires were started when San Francisco Fire Department firefighters, untrained in the use of dynamite, attempted to demolish buildings to create firebreaks. The dynamited buildings often caught fire. The city's fire chief, Dennis T. Sullivan, who would have been responsible for coordinating firefighting efforts, had died from injuries sustained in the initial quake. In total, the fires burned for four days and nights. Most of the destruction in the city was attributed to the fires, since widespread practice by insurers was to indemnify San Francisco properties from fire but not from earthquake damage. Some property owners deliberately set fire to damaged properties to claim them on their insurance. Captain Leonard D. Wildman of the U.S. Army Signal Corps reported that he "was stopped by a fireman who told me that people in that neighborhood were firing their houses...they were told that they would not get their insurance on buildings damaged by the earthquake unless they were damaged by fire" Source: Wikipedia
There is one forgotten detail about the new Madrid earthquake fault line here in Missouri-You forgot to mention that when the 1812 earthquake happened and when the Missouri river reversed flow going north word for a few, that all of the soils and surrounding banks around the Mississippi from St. Louis down to Memphis Tennessee, all had soil liquification happening such a severe case that even diaries and historical context from that earthquake can be found to show just how violent it really was.
I live in Santa Monica California (Los Angeles County) used to live in San Francisco. My house is new and built to current earthquake codes for California and the office I work in has been retrofitted to current California earthquake codes. I have a storm shelter with a month’s worth of food and supplies in the case of an actual earthquake emergency. I forgot to add the biggest earthquake I was in: Loma Prieta in San Francisco October 17th 1989. I was at the A’s-Giants World Series game! 15 seconds of pure adrenaline and fear! I’m glad I wasn’t on the Bay Bridge and especially not on the Cypress Expressway!
Wild to call the back-to-back 1811/1812 New Madrid quakes “less intense.” There’s a reason the USGS has labeled that region one of the most dangerous earthquake regions in the US. (It’s a failed continental rift that remains geologically active and tends to create massive quakes every few hundred years or so and has building codes that are woefully inadequate in a region that is severely economically depressed.) The other regions being Alaska, Cascadia, and the whole of the California coastal zone.
The whole Pacific Coast is waiting... Us for "The Big One" down here & Them for "Cascadia" up there. 12:13 I think Practical Engineering could model & test this lol.
What about the 7.3 that hit the Yucca Valley area in 92? It was a series of faults that fractured north of the San Andreas. My house had a crack that ran through from north to south across the street and beyond. There were foreshocks and many aftershocks. Could these series of quakes relieved some of the stress?
I think one element of this that you should touch which would probably require a whole video is the impact of blind thrust faults and the fact that there’s a huge blind thrust fault under downtown LA. Love your content
On February 27, 2010, I experienced the 8.8 magnitude earthquake in Chile, and as a structural engineer, I can tell you that if a 7.5 or higher earthquake strikes Southern California, the consequences could be devastating. About a third of the buildings may collapse, potentially resulting in thousands of deaths. Another third could catch fire due to disrupted water supplies, power outages, and limited access for firefighters, leading to even more casualties. The remaining third may fall victim to fires caused by rioting. And if the earthquake triggers a tsunami, it could claim thousands more lives. Be prepared, as such an event could happen at any time.
People forget that the Salton Sea as we know it is only about 150 years old created by a breach in the colorado river banks that diverted water into the Salton Sink. That's a blink in geologic time. It's doubtful that is going to affect the San Andreas fault in that short amount of time
Agreed. and remember it only averages 25 feet deep. How much does 25 feet of water weigh compared to the thousands of feet of rock beneath it (which weighs more than water.....duh).
1:16 that east-west fault is where the 7.0 and many after shocks happened today, Dec 05, 2024. It's called the Cascadia subduction zone, and it's major.
WHAT DISTURBS ME IS WHO IN THEIR RIGHT MIND WILL WANT TO WAIT FOR IT TO HIT LIKE YOU MENTIONED IN THE BEGINNING OF THE VIDEO , YOU SAID IT YOURSELF THAT THERE WOULD BE MAYHEM & CARNAGE NOBODY WILL EVER WANT TO GO THROUGH THAT 🤔🤔🤔🤔🤔🤔
When I was in middle school, my mom and friend had heard through social media that a scientist predicted the 'big one' was going to hit that week. I was too scared and stayed up each night until I couldn't keep my eyes open. That was more than 10 years ago. Now I'm like if it hits, it hits.
@@lezmkasd had an experience just like this was a kid in 6th grade and heard that on a specific day it would hit. I packed waters in my backpack and waited outside my house for it
it's funny, but to me "The Big One" refers primarily to the Cascadia Subduction Zone quake by default (i'm sure that's entirely unrelated to my living in Oregon lol)
I live in Central Texas and I have never felt an earthquake. My mother lived for about a year in Sacramento. She said they would leave in the morning and return to find the pictures were tilted. She never felt any quakes. Until she went to China. On the way back from an Elderhostel visit to China, the group was overnight in Japan, close to the airport in Tokyo. Her roommate that day was from California. She called my mother in and told her to sit on the bed. That was when suddenly the whole room was shaking. She told me that if she never felt another earthquake it would be too soon.
No one's in a hurry for the big one ....Easy.... Don't wake it.. I do not want to be all shook up. I'm more concerned about the PG&e hikes or why eggs are so much?
1994 I was living in New Hall. The apartments my parents and I lived in were new (the top of Lyons Ave by camping world) and the week after we unpacked our last box, we got the red flag on our building. People in panic were fleeing the area probably not aware on how badly damaged Interstate 5 was (not to mention the 14 (?) Heading towards Palmdale). I think the humorous side of it all is the shock started to wear off when the sun started to come up (people realized hair wasn't brushed, no makeup, everyone in boxers and pajamas).
4:30 WOW. This explains why there's that near-right angle of mountains near Lancaster. The Garlock fault and San Andreas fault meet there. I always wondered why the mountain ranges looked like that and the Lancaster area was just flat. It's a really bizarre thing to see basically 2 straight lines formed by nature on a map (can see it at 4:36)
Ca has never had a M8 quake and the SAF isn’t capable of a 9.0. Faults have limits. My theory is we’ve had our big one with a 7.9 in 1857 fort tejon and 1906 San Francisco. We’ve had several 7.0 size quakes since the 80’s
Been through 3 in L.A. 1971, 1987, and 1994. The '94 quake was over 7.0. It threw me out of my bed and destroyed my apartment. They called it 6.7 rumor had it so they insurance companies wouldn't have to make huge payouts. That one was big. Unlike rain, snow, tornados and hurricanes, they just cant predict earthquakes. They come out of nowhere.
Well, you stated that the weight of the Salton Sea could affect seismic activity in the area. The Salton Sea is about 300 sq miles while the San Francisco Bay is about 1600 sq miles. Twice a day SF Bay experiences tidal flow into and out of the bay, directly over the San Andeeas Fault. That's a massive weight of water yet no one discusses how that movement directly from one side to the other side of that fault is affecting seismic activity in that area.
I’m 48 and I’ve been hearing about the big one all my life and yet it has never yet come so I don’t know why but I haven’t seen anything past maybe a five at worst maybe six tops for California but it’s one of those unfortunate things to see everybody still talkingabout it
@@ChrisNoonetheFirst we’ve got faults up here too. I remember when mt st Helens blew. I was I Seattle for folklife festival and had to drive down I-5 to Corvallis past the Tuttle River. I was in Oakland when the Loma Prieta Earthquake hit, about 5 miles from the collapsed Cypress Structure. I’m waiting for the Cascadia fault on the San Juan de Fuca plate to go. Even with the volcanos and earthquakes, I prefer the west coast. Tornadoes terrify me. I guess it’s what you grew up with….
I think the New Madrid earthquake was maybe not the best example for eastern and Central U.S. earthquakes, which are as mentioned usually less frequent and less intense. The thing is the 1811-12 New Madrid earthquake was a monster of a quake, right up there with the 04 Sumatra and 11 Eastern Japan earthquakes. There was a quake on the Cape in 2011, it is over 4.0 on the Richter scale. Huge. Now that is a eastern U.S. quake.
@@jimmydee1130 Maybe not on the richter scale, but the seismic waves from those types of faults are felt much further away. There are reports that church bells rang as far away as New York and Boston. Those types of faults are left over from when the ice melted away after the last ice age. California is on a continental type of fault line, which is deeper and generally causes bigger quakes, but the waves do not travel as far, thus why you cannot feel a major quake from SF in LA and vice versa.
@@AslanKyoya1776 We've all heard the church bell stories. The relatively un-faulted eastern US allows seismic waves to travel undisturbed and for longer distances. The MORE faulted West absorbs and deflects seismic energy.
I was in 4th grade 1987 and experienced the Whittier quake. Several things happened with that one... it was my first quake i experienced. - A month after that the Weekly Reader, scholastic mini newspaper mentioned the potential of A BIGGER ONE IS COMMING. That scared me to death and i was scared of elevators and multi story buildings. That was the birth of claustrophobia to me. - My mom had to go to a corner store which we knew the owner well, back then EVERYTHING was in glass containers. The mess of broken glass was beyond anything i have seen. Just a couple years after that, products started coming in plastic containers (im sure the 1989 Loma Prieta quake also contributed to the PLASTIC CRAZE as well)
The New Madrid earthquakes were very intense. In fact they were the strongest earthquakes ever recorded in the lower 49 states, stronger than any that have occurred on the San Andreas Fault so far.
@@Zenflyn This is a very low IQ reply. You know the information is out there right and you can verify it for yourself. It's almost as if me saying that hit you personally LOL
California saw s 7.9 in 1853 and the 1906 earthquake was a 7.8. New Madrid quakes were probably a rough tie. New Madrid was the most widely felt quake. A quake east of the Rockies sends shock waves that are not intercepted by other geological features...sort of like hitting a bell. California's faults keep the effects of a quake within a smaller area...sort of like striking a rockpile with a sledge hammer. A 7.4 would disable transport across the Ohio and Mississippi Rivers for months. Buildings built since 1812 (almost all of them) would collapse in placee like St. Louis, Memphis and Louisville. Chicago would see serious damage. Every building east of the Mississippi would need inspection because a mere 6.0 in Western Virginia was enough to compromise buildings in DC.
Dang, and now seeing the uprise in seismic activity east of the Rockies is starting to get worrisome. First tornadoes and hurricanes, now they gotta deal with what California deals with geologically as well? Also, wasn't the 7.9 in 1857? And the 1906 San Francisco quake was more likely in the 8.0-8.3 range
@@S.K.R.E.Inc. Originally, the 1906 was thought to be an 8.3 and the New Madrid around 8.7. Now the 1906 is usually put at around 7.9 and New Madrid estimated at around 8.1 or so. And yes, earthquakes occur in the Midwest and California does get tornadoes although EF-0 or EF-1s at the most.
Where I lived in Southern California the Northridge quake shook for nearly two minutes. I lived through that one, the Sierra Madre Quake, the Whittier Narrows Quake that was about ten miles from my house, and damaged many older buildings. The Narrows quake popped steel riveted beams at the ALCOA plant where I worked. I also experienced many more quakes from 4 to 5 magnitude. Also since I’ve been retired living in El Paso we’ve had two here.
@@jimmydee1130 no it kept shaking where I lived close to the LA river, and had my kids freaked out because it wouldn’t stop shaking. Believe me I know the difference between 15 seconds and a minute or more.
@@gilgarcia3008 I was wrong. And so were you. REALLY wrong. "Lasting approximately 8 seconds and achieving the largest peak ground acceleration of over 1.7 g, it was the largest earthquake in the area since 1971". From Wikipeda. Take it up with the USGS. And living near the River has nothing to do with it.
Sadly even 3 decade's later many people have not met the earthquake codes here in San Fernando Valley, OMG gag me with a... yes that Valley! I'm ready to bug out! I always have a full tank in my 4x4 with camping supplies, food, water purification!
DO NOT say the words "OFTEN LESS INTENSE" and "NEW MADRID" in the same sentence! My ancestor broke his femor when the 1812 earthquake threw him against the roof of his cabin while he was asleep in bed!
Each of these faults have a direct connection to the Cascadia Fault. In 1700 the Cascadia shook a 9.0 and cause the San Andreas and Hayward Faults. It wasn't til later as of 3-5 years ago that the USGS came to this study and findings.
You also forgot to mention that over the past several months, Portland has had over a dozen shakers averaging 2.5. There was one back in 2001 that was a 4.6. And there was one along the coast that was felt in the Willamette Valley about 60 miles away around 88-89.
i remember in spring of 2005 my brother's girlfriend's mother thought that there was going to be the BIG one that summer, so she packed up (just the moster) and left the state and moved to Georgia. 19 years later and nothing...
The Big One is 90 years overdue. I studied the seismic history of NorCal & found big quakes at 60-80 year intervals. Big quakes flattened SF in the 1830's, 1850's, and 1880's. But SF was mostly smaller, wooden buildings then. So they didn't kill many. The 1849 Gold Rush changed that, and big masonry buildings and firetraps sprang up. The 1906 SF quake was the last Big One. My theory for the delay is that ice cap melting has taken gigatons off the poles, and spread it around the oceans. This has reduced the stresses on the Hayward and San Andreas faults, and put it on other older, long dormant faults.

@@rogaineablar5608 agreed. We also have the Garlock fault here in LA to worry about
The cascadia big one would cause the San andreas to trigger
@@rogaineablar5608 true, but san andreas is so close to densely populated areas, causing much more damage and deaths
What really worries me is that the Los Angeles Basin has a bunch of earthquake faults that are much shallower to ground level than the San Andreas Fault. These shallower faults means even a Magnitude 7.5 quake could cause a huge amount of destruction and casualties on their own.
I remember in a geography of CA class I took in 2010 that the "big one" could happen at any time on a geologic time scale. Meaning, it can happen any time in the next few hundreds of thousands, if not millions of years.
🤣😂🙏🍀🌠 after rereading your comment Mr. Toast.
or more likely never as all those vulcanic placess are now more or less death after the big earthquake was in california ....
SO IT HAD BEEN already and NOT GOING TO
Human Time vs. Geologic Time. The southern San Andreas can have intervals of 100 years to 400 years between events. Your Grandchildren may miss the next one. Besides - the splinter faults closer to populated areas likely pose a bigger danger
😮😮😮
exactly. the Newport-inglewood fault could disrupt all 6 major highways on the west side. we also have a major off shore strike-strip fault that runs from santa monica to the mexican boarder that isn’t widely understood, but they know it can produce upwards of a 7.9.
Not to mention, human activity may delay the quake beyond the geological precedent.
@@myweirdsecondchannelwithap9070 Human activity? Goodness gracious what are you talking about? Are you daft?
Whos here after their 7.0 magnitude earthquake
That was way overstated.

nothing even happened with it
I grew up in Southern California and experienced the February 1971 Sylmar (San Fernando) earthquake at age 7. It hit right at 6:00 AM PST, and was of magnitude 6.6.
I lived about 33 miles from the epicenter so it wasn't bad where I was. It was severe enough to kill 65 people in the San Fernando Valley area, most of them in the Olive View and VA hospitals.
We were VERY lucky that it happened at 6 AM and not an hour or two later, when the freeways would have been clogged with cars. Overpasses collapsed at the junction of the 5 and 210 freeways.
It would have been hundreds dead, if not more.
I was there too ---Inglewood-- there are no atheists during a major earthquake -- people all start praying to God.
The Loma Prieta one was far worse. That one hit HARD where I was. I won't go into it, but that was a lllooonnng DAY. 😂🤣😂
I was 13, and lived 9 miles from the epicenter of the 71' Sylmar quake. And l have been through every other major earthquake in Southern California including the Northridge, Whittier, Landers, Big Bear etc. All of them within 30 miles of the epicenters !. The Big One, will make all of those seem like a tremor. It will be the most traumatic experience any individual will go through in their lifetime. Even soldiers that have been to war !.

Here in New Zealand, we're also waiting the "The Big One" to send our capital city of Wellington back underwater.
In 2011 a big one hit... and destroyed Christchurch, a city previously thought of reasonably safe.
This would be the equivalent of expecting a big quake to hit Los Angeles, only to have Las Vegas get destroyed instead.
@@rad4924 I was scrolling the comments looking for a kiwi to comment about how 'we are waiting for "Our The Big One." to hit Wellington.' while shaking my head no why do you have to question where is it.
Completely agree with what you said about Christchurch they thought they were safe and then got hit by three big quakes in span of 18 months and 1000s of aftershocks for years after.
Everyone thought the South Island was safe from big quakes, since most active fault lines were in the North Island.
You mean Portland, right? It's not the LA area geologists are really worried about, but Cascadia.
We have the same kinda thing here... we call it "Draining the swamp"
I'm 50. When I was in elementary school, there were urban legends of "the big one" where California was going to break off and fall into the ocean, just like at the beginning of this video. We used to do "earthquake drills" to prepare for it. So I can say with confidence that this talk of "the big one" has been going on for at least 40 years.
since I been in high school in 80s there has been talk, Northridge was big not like the one they talked about
Yeah but it is gonna happen just we dont know when so being ready is the best thing we can do. At this point if it dose happen 95% of people are absolutely FUCKED because NO ONE is ready. Everyone thinks im crazy but it will ALWAYS be better to be SAFE THEN SORRY. Geological time is wild and we will never be able to fully predict it we can just be ready for when it happens. But sadly i dont think hiding under a school desk if gonna save ANY of us californians esp with how everyone thinks its a joke now. All i can say is god help us when it happens because no one thought the hurricanes the us just had were gonna be bad either and now look at the destruction thats caused. We can NEVER know when its gonna happen. We CAN just be ready.
I'm 64 and we had the same stories.
I'm 66 years old and I grew up with the same stories .when I was 9 years old in 1968 I had heard that the big earthquake was suppose to sink California into the ocean.

I was in the Primm Valley Casino (on the Nevada-California border) when the Hector Mine earthquake struck on October 16, 1999. The giant chandeliers swayed back and forth, the floor rumbled, and dust fell from a trembling ceiling. Some people fled the casino, but no damage resulted from the magnitude 7.1 quake. Since that time, I've felt a few gentle rollers here in Las Vegas. But they didn't originate from the fault lines located right here in the city.
Watching from Los Angeles we have had a bunch of smaller 4-5 point quakes recently too. A little more than what feels normal at least to someone who’s lived here for decades. That could be part of it as the smaller quakes could be releasing some of that potential energy. Malibu, South Pasadena and other areas have been hit with quakes that size recently and felt them all in the downtown area very strongly.
@@scottclapson exactly. we’ve been getting a lot of earthquakes lately, and even though they’re just rumbles it makes me wonder if the big one is coming soon

I think the West Coast oughter more worry about the Cascadia than the San Andreas. Cascadia will be the more disastrous that'd make the worst the San Andreas can do look minor in comparison.
Agreed though it very well could trigger the San Andreas as well. CSZ isn't talked about enough but it does finally seem to be getting more recognition the last decade
@ Yup, I'd be VERY surprised when the Cascadia does cut loose that it doesn't trigger reactionary slips in the surrounding fault lines. The earth is one big complex tangle of interlocking plates. If a big one cuts loose in one spot, that's bound to affect the tensions in the surrounding plates' fault lines.
This video was disappointing. Talks very little about San Andreas for the first 10 minutes. Never says why they expect there to be a big one, never shows if any criteria has been met, and never shows any clues to whether or not it’s getting close.
Agreed. And all the focus on the Salton Sea!!!! The Salton is very very shallow - avg 26 feet. It's not like removing the "weight" of it will matter much. That valley was completely dry from 1500 to 1907, don't forget.
I agree also. 15 minutes of backstory only to say we don’t know. Clickbait. This author is “pushing” videos on Instagram so I’m going to block that user.

Never mentioned the "Landers/Big Bear " twin quakes ! 7.3 and 6.6 3 hours apart. One dozen aftershocks above 5.5 over the next 2 years. Then 6 years later in the same region, the 29 palms 7.0 . There was really something going on in that region of Southern California at that time. It tore a crack in the earths crust 56 miles long with up to 12 feet displacement.
I remember visiting California in 2019 during the Ridgecrest earthquakes-felt a small tremor but nothing like the 'Big One' everyone talks about. It's surprising how it hasn't happened yet, despite all the predictions!
Because you were likely well over 100 miles way.
there are no real pridictions just news hype as long as california has regular earrth quakes to relive stress on the san andreas things will be ok the coastal plate is moving north and will always do that . the worst thing is to not have small earthquakes which will make the big one worse.
I live in Michigan and like 10 ish years ago we actually had a tiny earthquake and I felt it! I was sitting in my kitchen and felt my house wobble slightly, at first I thought maybe the washing machine was unbalanced. I'm so glad we don't have big serious earthquakes here!
As somebody from Mississippi, I am glad that we don't got earthquakes too! 😂👌 Hurricanes are our own catastrophic events that is even more scarier. Same way with tornados but tornados happen out of nowhere randomly just like earthquakes.
I remember my father talking about it in the 70's!
I was 14 yo living in Northridge during the Northridge earthquake. Many people had to camp in public parks because we lost our homes. Crazy times.
The BIG ONES occur on subduction zones. SoCal is nowhere near a subduction zone. The type of shaking for minutes just dont happen nearly as often and if a large quake occurs, it lasts for seconds, not minutes
😮
Actually, there are two plates off the North California coast that are subducting which have created at least two known volcanos: Mount Lassen and Mount Shasta.
@BelwonsenorSimpkriss NoCal ...yes... not SoCal ....though there is a lesser known super volcano which forms the mono lake area. Im convinced if the moon did form from Earth colliding with another smaller planet, the ring of fire is the scab.
@@quaoar213 Interesting idea. That or maybe the impact was a little to the east over Micronesia which may have been an intact continent before the event.
@BelwonsenorSimpkriss There is a legend of Land or continent in the pacific .
At least the highest the San Andreas can produce is 8.3. I think people should be more focus on Cascadia (The really Big One) rather than just California because that can produce tsunamis unlike San Andreas.

I sometimes feel earthquakes here in SoCal. I’m afraid the big one will come minutes after a smaller one. Knowing myself I’m sure I’m going to end up sleeping through the big one. Had so many mornings when my family would ask “did you feel the earthquake last night?”
In 2011, The Washington D.C. area experienced a minor quake. I live in Maryland and we felt it. It wasn't that bad, but it did cause some cracking damage to the Washington Monument and some other stone buildings in the area. I also heard some say the foundation of their houses were cracked.
How bad was the monument cracking?
I lived in Northern Virginia then and remember it! As a native Californian, I was so freaked out to feel a significant shake on the opposite coast and I remember seeing the cracks in the Washington Monument. A quake doesn't have to be very large to cause problems in that area!

The 1906 San Fransisco earthquake is when the entire city committed Insurance fraud, nobody had "Earthquake Insurance" but a lot of folks had "Fire Insurance" so the city burned for 3 days
@paulthomson2466 interesting I would like to know how well our firefighter infrastructure back then
@@rayrayrun Not very good, they used horse back then. Plus Some of the fires were started when San Francisco Fire Department firefighters, untrained in the use of dynamite, attempted to demolish buildings to create firebreaks. The dynamited buildings often caught fire. The city's fire chief, Dennis T. Sullivan, who would have been responsible for coordinating firefighting efforts, had died from injuries sustained in the initial quake. In total, the fires burned for four days and nights.
Most of the destruction in the city was attributed to the fires, since widespread practice by insurers was to indemnify San Francisco properties from fire but not from earthquake damage. Some property owners deliberately set fire to damaged properties to claim them on their insurance. Captain Leonard D. Wildman of the U.S. Army Signal Corps reported that he "was stopped by a fireman who told me that people in that neighborhood were firing their houses...they were told that they would not get their insurance on buildings damaged by the earthquake unless they were damaged by fire" Source: Wikipedia
There is one forgotten detail about the new Madrid earthquake fault line here in Missouri-You forgot to mention that when the 1812 earthquake happened and when the Missouri river reversed flow going north word for a few, that all of the soils and surrounding banks around the Mississippi from St. Louis down to Memphis Tennessee, all had soil liquification happening such a severe case that even diaries and historical context from that earthquake can be found to show just how violent it really was.
Well done, my dad wanted to see the big one, he passed away age 65 in 2013
Trying to predict when the next earthquake will strike is like trying to predict in what order all the regular customers will arrive at a coffee shop.
I live in Santa Monica California (Los Angeles County) used to live in San Francisco. My house is new and built to current earthquake codes for California and the office I work in has been retrofitted to current California earthquake codes. I have a storm shelter with a month’s worth of food and supplies in the case of an actual earthquake emergency.

I think I just felt it at 3ish am 😢😢 my heart is still pounding! Hope everyone is safe.
Wild to call the back-to-back 1811/1812 New Madrid quakes “less intense.” There’s a reason the USGS has labeled that region one of the most dangerous earthquake regions in the US. (It’s a failed continental rift that remains geologically active and tends to create massive quakes every few hundred years or so and has building codes that are woefully inadequate in a region that is severely economically depressed.) The other regions being Alaska, Cascadia, and the whole of the California coastal zone.
The reason is bc caseoh is still learning how to jump and eventually he will

Where the San Andreas stops, the Cascadia begins at Cape Mendocino. A strike slip to a subduction zone. Are to two related? I think so.
I would love to see that video
It’s not our fault, it’s San Andreas’ fault.
What about the 7.3 that hit the Yucca Valley area in 92? It was a series of faults that fractured north of the San Andreas. My house had a crack that ran through from north to south across the street and beyond. There were foreshocks and many aftershocks. Could these series of quakes relieved some of the stress?
Does removal of oil from the ground help cause earthquakes?
I think you are referring to "fracking", which is a way to collect "natural gas".
Fracking causes earthquakes, The largest fracking quake occurred in Coalinga, California--a 6.5--in 1983.
I think one element of this that you should touch which would probably require a whole video is the impact of blind thrust faults and the fact that there’s a huge blind thrust fault under downtown LA. Love your content
1857 Fort Tejon earthquake Magnitude 7.9
Just how does a lake that is only a hundred years old affect a 35 million year old fault line.
This aged well
On February 27, 2010, I experienced the 8.8 magnitude earthquake in Chile, and as a structural engineer, I can tell you that if a 7.5 or higher earthquake strikes Southern California, the consequences could be devastating. About a third of the buildings may collapse, potentially resulting in thousands of deaths. Another third could catch fire due to disrupted water supplies, power outages, and limited access for firefighters, leading to even more casualties. The remaining third may fall victim to fires caused by rioting. And if the earthquake triggers a tsunami, it could claim thousands more lives. Be prepared, as such an event could happen at any time.
People forget that the Salton Sea as we know it is only about 150 years old created by a breach in the colorado river banks that diverted water into the Salton Sink. That's a blink in geologic time. It's doubtful that is going to affect the San Andreas fault in that short amount of time
Agreed. and remember it only averages 25 feet deep. How much does 25 feet of water weigh compared to the thousands of feet of rock beneath it (which weighs more than water.....duh).
1:16 that east-west fault is where the 7.0 and many after shocks happened today, Dec 05, 2024. It's called the Cascadia subduction zone, and it's major.

@@lezmkasd had an experience just like this was a kid in 6th grade and heard that on a specific day it would hit. I packed waters in my backpack and waited outside my house for it
it's funny, but to me "The Big One" refers primarily to the Cascadia Subduction Zone quake by default (i'm sure that's entirely unrelated to my living in Oregon lol)
I think you’re right, the real big one is the cascadia fault
I live in Central Texas and I have never felt an earthquake. My mother lived for about a year in Sacramento. She said they would leave in the morning and return to find the pictures were tilted. She never felt any quakes. Until she went to China. On the way back from an Elderhostel visit to China, the group was overnight in Japan, close to the airport in Tokyo. Her roommate that day was from California. She called my mother in and told her to sit on the bed. That was when suddenly the whole room was shaking. She told me that if she never felt another earthquake it would be too soon.
Superman stopped Lex Luthor's stolen missle from hitting the fault line years ago. No Marina Del Lex.

1994 I was living in New Hall. The apartments my parents and I lived in were new (the top of Lyons Ave by camping world) and the week after we unpacked our last box, we got the red flag on our building.
People in panic were fleeing the area probably not aware on how badly damaged Interstate 5 was (not to mention the 14 (?) Heading towards Palmdale).
I think the humorous side of it all is the shock started to wear off when the sun started to come up (people realized hair wasn't brushed, no makeup, everyone in boxers and pajamas).
The Big One is also expected here in Oregon with Portland expected to get worse of it.
Cascadia

Ca has never had a M8 quake and the SAF isn’t capable of a 9.0. Faults have limits. My theory is we’ve had our big one with a 7.9 in 1857 fort tejon and 1906 San Francisco. We’ve had several 7.0 size quakes since the 80’s
You can’t talk about earthquakes and not talk about Loma Prieta!
Been through 3 in L.A. 1971, 1987, and 1994. The '94 quake was over 7.0. It threw me out of my bed and destroyed my apartment. They called it 6.7 rumor had it so they insurance companies wouldn't have to make huge payouts. That one was big. Unlike rain, snow, tornados and hurricanes, they just cant predict earthquakes. They come out of nowhere.
Well, you stated that the weight of the Salton Sea could affect seismic activity in the area.
The Salton Sea is about 300 sq miles while the San Francisco Bay is about 1600 sq miles.
Twice a day SF Bay experiences tidal flow into and out of the bay, directly over the San Andeeas Fault.
That's a massive weight of water yet no one discusses how that movement directly from one side to the other side
of that fault is affecting seismic activity in that area.

The same thing happened before the January 1994 6.7 Earthquake. I firmly believe smaller quakes occur before a major quake.
Video starts at 10:24
The answer to the thumbnail is revealed at 11:50
I think the New Madrid earthquake was maybe not the best example for eastern and Central U.S. earthquakes, which are as mentioned usually less frequent and less intense. The thing is the 1811-12 New Madrid earthquake was a monster of a quake, right up there with the 04 Sumatra and 11 Eastern Japan earthquakes. There was a quake on the Cape in 2011, it is over 4.0 on the Richter scale. Huge. Now that is a eastern U.S. quake.
New Madrid was nothing of the sort - nowhere near the intensity of a major subduction quake.
@@jimmydee1130 Maybe not on the richter scale, but the seismic waves from those types of faults are felt much further away. There are reports that church bells rang as far away as New York and Boston. Those types of faults are left over from when the ice melted away after the last ice age. California is on a continental type of fault line, which is deeper and generally causes bigger quakes, but the waves do not travel as far, thus why you cannot feel a major quake from SF in LA and vice versa.
@@AslanKyoya1776 We've all heard the church bell stories. The relatively un-faulted eastern US allows seismic waves to travel undisturbed and for longer distances. The MORE faulted West absorbs and deflects seismic energy.
I was in 4th grade 1987 and experienced the Whittier quake. Several things happened with that one... it was my first quake i experienced.
- A month after that the Weekly Reader, scholastic mini newspaper mentioned the potential of A BIGGER ONE IS COMMING. That scared me to death and i was scared of elevators and multi story buildings. That was the birth of claustrophobia to me.
- My mom had to go to a corner store which we knew the owner well, back then EVERYTHING was in glass containers. The mess of broken glass was beyond anything i have seen. Just a couple years after that, products started coming in plastic containers (im sure the 1989 Loma Prieta quake also contributed to the PLASTIC CRAZE as well)
The New Madrid earthquakes were very intense. In fact they were the strongest earthquakes ever recorded in the lower 49 states, stronger than any that have occurred on the San Andreas Fault so far.
were you there did you feel it? then no proof
@@Zenflyn This is a very low IQ reply. You know the information is out there right and you can verify it for yourself. It's almost as if me saying that hit you personally LOL
California saw s 7.9 in 1853 and the 1906 earthquake was a 7.8. New Madrid quakes were probably a rough tie.
New Madrid was the most widely felt quake. A quake east of the Rockies sends shock waves that are not intercepted by other geological features...sort of like hitting a bell. California's faults keep the effects of a quake within a smaller area...sort of like striking a rockpile with a sledge hammer.
A 7.4 would disable transport across the Ohio and Mississippi Rivers for months. Buildings built since 1812 (almost all of them) would collapse in placee like St. Louis, Memphis and Louisville. Chicago would see serious damage. Every building east of the Mississippi would need inspection because a mere 6.0 in Western Virginia was enough to compromise buildings in DC.
Dang, and now seeing the uprise in seismic activity east of the Rockies is starting to get worrisome. First tornadoes and hurricanes, now they gotta deal with what California deals with geologically as well? Also, wasn't the 7.9 in 1857? And the 1906 San Francisco quake was more likely in the 8.0-8.3 range
@@S.K.R.E.Inc. Originally, the 1906 was thought to be an 8.3 and the New Madrid around 8.7. Now the 1906 is usually put at around 7.9 and New Madrid estimated at around 8.1 or so. And yes, earthquakes occur in the Midwest and California does get tornadoes although EF-0 or EF-1s at the most.

Each of these faults have a direct connection to the Cascadia Fault. In 1700 the Cascadia shook a 9.0 and cause the San Andreas and Hayward Faults. It wasn't til later as of 3-5 years ago that the USGS came to this study and findings.
The big one left, cost of living was too high .
You also forgot to mention that over the past several months, Portland has had over a dozen shakers averaging 2.5. There was one back in 2001 that was a 4.6. And there was one along the coast that was felt in the Willamette Valley about 60 miles away around 88-89.
its stuck in another multiverse .
Sooooo where can we get that map of CA you were promoting in that add? I found your website but the shop was empty 😬
Evidence suggests that whenever the whole length of Cascadia ruptures, San Andreas also experiences a "big one"
i remember in spring of 2005 my brother's girlfriend's mother thought that there was going to be the BIG one that summer, so she packed up (just the moster) and left the state and moved to Georgia. 19 years later and nothing...
i moved to SF in Aug 1989, a month before the loma pretta earthquake. i don't live in CA anymore so maybe they should thank me!
"Near Future" is relative
They've been saying that for ages. I was 8 years old when I first heard it now I'm 48. I lived in LA as a child so I was scared.
The Big One is 90 years overdue.
I studied the seismic history of NorCal & found big quakes at 60-80 year intervals. Big quakes flattened SF in the 1830's, 1850's, and 1880's. But SF was mostly smaller, wooden buildings then. So they didn't kill many. The 1849 Gold Rush changed that, and big masonry buildings and firetraps sprang up. The 1906 SF quake was the last Big One.
My theory for the delay is that ice cap melting has taken gigatons off the poles, and spread it around the oceans.
This has reduced the stresses on the Hayward and San Andreas faults, and put it on other older, long dormant faults.
as a casual student of the radical theory of plate tectonics in the 1960’s I found this fascinating. thanks.
Very good research young man.
